I'm not sure whether I should be worried or not.

We finally got cable broadband in our area. We have a Network Everywhere (Linksys) router NR041-WM connected to our DSL modem and 2 computers.

I checked at grc and it shows Ports 23 and 80 as open, which is the concern. I activated Win Firewall and the ports still show open. I've also read that in the case of routers, grc and others might not be right, and the ports are still protected. I'm running the router with default settings since I, obviously, know absolutely nothing about the things, and because the wife would kill me if I screwed things up and she couldn't get online with her computer.

Should these ports read open or not? If not, anyone have any ideas on how to close or stealth them? Remember, you're talking to a techno-idiot.
